A scientist says one of the most sought after particles in physics - the Higgs boson - may have been found, but the evidence is still relatively weak. Peter Renton, of the University of Oxford, says the particle may have been detected by researchers at an atom-smashing facility in Switzerland. The Higgs boson explains why all other particles have mass and is fundamental to a complete understanding of matter. Dr Renton's assessment of the Higgs hunt is published in Nature magazine. "There's certainly evidence for something, whether it's the Higgs boson is questionable," Dr Renton, a particle physicist at Oxford,...
